Looks like an awful lot of stretch, possibly from using Superthrive during flower. The growth hormones and nitrogen in it are likely delaying the flowering process, too. A week or so after flushing, likely they will return to full flowering state.

But to cover all bases, how close do you keep the light to the ladies? Are they stretching to reach the light?

In picture hpim252 (top left) you show signs of ph imbalance. What I was taught was 'canoeing', but is sometimes refered to as 'the claw'. What's your water ph, and if you know...what's the runoff ph?

In my flower shed, during the summer, I'd give my left nut to get temps down to 82. :thumbsup
